- LEATHER-Enema TOOL.

Specification of Letters Patent. Patented NCV. 23, 1909.

Application filed January 14, 1909. Serial No. 472,377.

To all whom it may concern:

Be it known that I, MARGARET CUMMs, a citizen of the United States ofAmerica, and a resident of Chicago, in the county of Cook and State ofIllinois, am the eXecutriX of the estate of FRANK F. CUMMs, late acitizen of said city, and that the said FRANK F. CUMMs did invent acertain new anduseful Improvement in Leather-Edging Tools,

and I do declare the following'to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in leather edging tools. V

The object of-the inventionis to provide a tool of this character bymeans of which the edges of leather straps may be smoothly and evenlytrimmed.

A further object of the invention is to provide an edge trimmer forleather straps and the like having means whereby the same may be quicklyand easily adjusted for use on straps of different thicknesses.

With these and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts aswill be described and particularly pointed out in the appended claims.

In the accompanying drawing, Figure 1 is a plan view of the tool showingin dotted lines the manner of adjusting the gaging lever; and Fig. 2 isa longitudinal sectional view of the same; and Fig. 3 is a transversesectional view on the line 3-3 of Fig. 1.

Referring more particularly to the drawings 1 denotes the edger whichconsists of a blade, 2, on one end of which is formed a shank, 3, bymeans of which the blade is enaged with a suitable handle, 4.

The upper side of the blade 2 is cut away to form a centrally disposedcutting edge, 5, on the outer end of the blade 2. The portions of theblade adjacent to its opposite edges form guide flanges, 6, said flangededges being formed by the recessed or cutaway portion of the blade andthey serve as guides for the work upon which the tool is used. Theflange, 6, on one side of the blade projects a short distance beyond thecutting edge as shown at 7, and forms a guide lug by means of which theend of the blade may be more readily engaged with the edge of theleather to be trimmed.

Pivotally mounted on the upper side of the blade adjacent to one edge ofthe same is a gaging lever, 8, the forward end of which is turneddownwardly at right-angles over the outer end of the blade and forms aguide lug, 9. The lever, 8, is pivotally connected to the blade by apivot screw, 10, on which is arranged a thumb nut, 12. On the inner endof the lever, 8, is formed a rightangular extension, 13, in which and inthe end of the lever is formed a transversely disposed slot, 14, toreceive a set screw, 15,

which is adapted to be screwed into a threaded aperture in the bladewhereby the lever is held in its adjusted position. The "rear portionof, the leverbetween the pivot screw, 10, and the set screw 15 isreduced in thickness so that said rear portion of the lever forms aspring whereby when the thumb nut 12 is screwed outwardly on the pivotbolt, the forward end of the lever will spring upwardly out ofengagement with the end of the blade, thereby facilitating the pivotalmovement of the lever to adjust the downwardly turned end, 9, therebyincreasing or decreasing the working space of the blade between said end9 and the projecting end, 7 of the flange, 6. When thus adjustin thelever, the set screw, 15, is loosened sui iiciently to permit theslotted inner end of the lever to move freely in one direction or theother across the blade. After the lever has thus been adjusted toprovide the desired width of working space for the cutting edge of theblade, the thumb nut is screwed inwardly on the pivot bolt, therebyclamping the lever firmly into engagement with the upper side of theblade, after which the set screw is again tightened and securely holdsthe lever in position.

By means of a tool of this character, the edges of straps or similarobjects may be smoothly and evenly trimmed in a safe and efiicientmanner.

A tool as herein shown and described is simple, strong and durable inconstruction and well adapted to the purpose for which it is designed.

From the foregoing description, taken in connection with theaccompanying drawing, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to Without departing from the principle orsacrificing any of the advantages of the invention as defined in theappended claims.

Having thus described the invention, what is claimed as new and desiredto bessecured by Letters-Patent, is:

1. In an edge trimmer of the character de scribed, a blade having on itsouter end'a cutting edge, guide flanges formed on the opposite edges ofthe blade, a guide lug projecting beyond the end of the: blade at oneside of said cutting edge,.and an adjustable gaging lever to co act withsaid flange and guide lug.

2. In an edge trimmer ofthe character described, a'blade having formedonvone end a cutting edge, a guide lug on one side of said.

edge, a guide lever having-a right angularly formedguidelug onits-outerend, and a transversely slotted extension onits rear end, a pivotscrewto pivotally connect said lever with the blade, and a set'ascrewarranged in the slotted inner end of the lever to hold the same in itsadjusted positionyon the blade- 3.In an edge trimmer of the characterdescribed, a blade having on its outer end a cutting edge, a guideflange and lug on one side of said edge, a guide lever having aright-angularly formed guide lug on its outer. end, and a transverselyslotted extension on its inner end, a pivot screw to pivotally connectsaid lever with the blade, a thumb nut on said screw adapted to clampthe lever into engagementwith the blade, a set. screwinlthe-slottedinner end of the lever whereby the-latter is held initsadjusted position, and a spring formed in the rear portion of. the leverwhereby the for- Ward end thereof is disengaged from the outer-'endofthe blade when said thumb nut isunscrewed.

In testimony whereof, I have hereunto setsmyihandinthe presence oftwosubscribing witnesses MARGARET CUMMS, Emecutm'ae of Frank F. Gumms,deceased.
